In this video I want to talk about WLAN. When people say WLAN, they usually mean wireless internet or Wi-Fi or Wi-Fi hotspot. WLAN literally means wireless local area network.
We're talking about a local area network created by something like this, a wireless router. This wireless router will plug into your internet modem and will take that internet and share it wirelessly through a radio signal with all your Wi-Fi or WLAN compatible devices, like this laptop or your phone or your tablet or even your TV.
The network that this wireless hotspot creates is not as fast as one you will get with a regular LAN, which is by connecting it to an Ethernet cable. It is very, very convenient, and it lets you have internet in places that you would not normally have internet in or that would be really hard to get internet in.
The nice thing about wireless LAN is that it enables you to sit on the sofa with your laptop, not having any cables around and still get the full internet without any speed issues or limitations.
Basically WLAN is just another way of saying Wi-Fi or hotspot, and that's the way it works.
